The PB Membrane Pore Size Analyzer utilizes the gas-liquid or liquid liquid displacement method (bubble pressure method) to accurately measure the pore size characteristics of membrane materials. By applying a pressure difference across the membrane, the system overcomes the surface tension of the infiltration liquid, driving it through the pores to determine pore throat sizes. This method is the standard for ASTM thin film pore size testing. The analyzer is widely used for pore size analysis in materials such as filter membranes, fiber membranes, filter elements, battery separators, fabrics, non-woven fabrics, paper, ceramics, sintered metals, rocks, concrete, and more.
